Heinz Mauelshagen 36cac41115 man-generator/man/help: simplify hyphen escaping
Commits a29bb6a14b
    ... 5c199d99f4
narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts.  This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.

On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.

Changes:
- revert the above commits whilst keeping man-generator
  streamlining and the detection of any '\' when generating
  help texts in order to avoid escapes to slip in

- Dynamically escape hyphens in manaual pages using sed(1)
  in the respective Makefile targets

- remove any manually added escaping on hyphens from any
  static manual sources or headers

blkdeactivate \(em utility to deactivate block devices
.SH SYNOPSIS
.B blkdeactivate
.RB [ -d \ \fIdm_options\fP ]
.RB [ -e ]
.RB [ -h ]
.RB [ -l \ \fIlvm_options\fP ]
.RB [ -m \ \fImpath_options\fP ]
.RB [ -u ]
.RB [ -v ]
.RI [ device ]
.SH DESCRIPTION
The blkdeactivate utility deactivates block devices. For mounted
block devices, it attempts to unmount it automatically before
trying to deactivate. The utility currently supports
device-mapper devices (DM), including LVM volumes and
software RAID MD devices. LVM volumes are handled directly
using the \fBlvm\fP(8) command, the rest of device-mapper
based devices are handled using the \fBdmsetup\fP(8) command.
MD devices are handled using the \fBmdadm\fP(8) command.
.SH OPTIONS
.TP
.BR -d ", " --dmoption \ \fIdm_options\fP
Comma separated list of device-mapper specific options.
Accepted \fBdmsetup\fP(8) options are:
.RS
.IP \fIretry\fP
Retry removal several times in case of failure.
.IP \fIforce\fP
Force device removal.
.RE
.TP
.BR -e ", " --errors
Show errors reported from tools called by \fBblkdeactivate\fP. Without this
option, any error messages from these external tools are suppressed and the
\fBblkdeactivate\fP itself provides only a summary message to indicate
the device was skipped.
.TP
.BR -h ", " --help
Display the help text.
.TP
.BR -l ", " --lvmoption \ \fIlvm_options\fP
Comma-separated list of LVM specific options:
.RS
.IP \fIretry\fP
Retry removal several times in case of failure.
.IP \fIwholevg\fP
Deactivate the whole LVM Volume Group when processing a Logical Volume.
Deactivating the Volume Group as a whole is quicker than deactivating
each Logical Volume separately.
.RE
.TP
.BR -m ", " --mpathoption \ \fImpath_options\fP
Comma-separated list of device-mapper multipath specific options:
.RS
.IP \fIdisablequeueing\fP
Disable queueing on all multipath devices before deactivation.
This avoids a situation where blkdeactivate may end up waiting if
all the paths are unavailable for any underlying device-mapper multipath
device.
.RE
.TP
.BR -u ", " --umount
Unmount a mounted device before trying to deactivate it.
Without this option used, a device that is mounted is not deactivated.
.TP
.BR -v ", " --verbose
Run in verbose mode. Use --vv for even more verbose mode.
.SH EXAMPLES
.
Deactivate all supported block devices found in the system, skipping mounted
devices.
.BR
#
.B blkdeactivate
.BR
.P
Deactivate all supported block devices found in the system, unmounting any
mounted devices first, if possible.
.BR
#
.B blkdeactivate -u
.BR
.P
Deactivate the device /dev/vg/lvol0 together with all its holders, unmounting
any mounted devices first, if possible.
.BR
#
.B blkdeactivate -u /dev/vg/lvol0
.BR
.P
Deactivate all supported block devices found in the system. If the deactivation
of a device-mapper device fails, retry it. Deactivate the whole
Volume Group at once when processing an LVM Logical Volume.
.BR
#
.B blkdeactivate -u -d retry -l wholevg
.BR
.P
Deactivate all supported block devices found in the system. If the deactivation
of a device-mapper device fails, retry it and force removal.
.BR

.B blkdeactivate -d force,retry
