If e.g. /bin is a symbolic link, it is canonicalized into /usr/bin, so
packages get auto-generated dependencies on paths like /usr/bin/sh and
/usr/sbin/blkid.
Here is an example error message:
The following packages have unmet dependencies:
chrooted: Depends: /usr/bin/sh but it is not installable
PreDepends: /usr/bin/sh but it is not installable
E: Broken packages
hsh-install: Failed to calculate package file list.
hsh-install: Failed to generate package file list.
Try to work around this by replacing the current sorta-canonicalization
written in shell with a small C program which implements an algorithm
akin to realpath. It deviates from `realpath` and `readlink -e` in 3
following ways:
* it allows all path components to be missing, like `readlink -m` and
like the previous CanonPath impl);
* it ignores the last path component even if it is present, like the
previous CanonPath impl;
* it reserves the right to not follow some symlinks as each path
component is traversed: if the component is a symbolic link and is
present in the ignore-list (we set it to /bin and /sbin for now), the
link is not followed.
Here are some observations on a merged-usr system:
bash-5.2# readlink -vm -- /bin/sh
/usr/bin/sh5
bash-5.2# /bin/sh -ec '. /usr/lib/rpm/functions; CanonPath /bin/sh'
/usr/bin/sh
bash-5.2# /usr/lib/rpm/remappath2 '/bin:/sbin' /bin/sh
/bin/sh
bash-5.2# readlink -vm -- /bin/ping
/usr/libexec/ping/ping
bash-5.2# /bin/sh -ec '. /usr/lib/rpm/functions; CanonPath /bin/ping'
/usr/bin/ping
bash-5.2# /usr/lib/rpm/remappath2 '/bin:/sbin' /bin/ping
/bin/ping
bash-5.2# readlink -vm -- /sbin/blkid
/usr/sbin/blkid
bash-5.2# /bin/sh -ec '. /usr/lib/rpm/functions; CanonPath /sbin/blkid'
/usr/sbin/blkid
bash-5.2# /usr/lib/rpm/remappath2 '/bin:/sbin' /sbin/blkid
/sbin/blkid
Also, explicitly add -D_FILE_OFFSET_BITS=64 to the remappath2 tool's
cflags.
