Michael Shigorin	d7689f30c7	tar2vm: rewrote as tar2fs ... Overview of the changes: - ARM support: separate ext2 /boot, no LILO - avoid race condition with devmapper - trap ERR so that -e in shebang doesn't result in extra cleanup hassle - configurable root filesystem type (ext4 by default) - jumps through parted hoops Details: 1. LILO is x86-specific while the rest of the script can be used to prepare e.g. Marvell ArmadaXP or CuBox images; we can generally count on uboot supporting ext2 for relatively sane platforms but not ext4 that would be a better root filesystem performance-wise. 2. Apparently /dev/mapper/loopXpY can be still missing at the time when kpartx returns and pop up a bit later... sit there, wait and check for it. 3. If something went wrong with any command of the script it would bail out due to -e in shebang; it is now better to clean up the loopback device and its mappings in this situation either. 4. One size doesn't fit all, really. 5. The parted sizing was sloppy as in broken, now it's just half insane. Someone's decision to stick units and auto-alignment knobs into a single one was apparently hilarious... http://www.gnu.org/software/parted/manual/parted.html#unit Manual loop/dm cleanup is described in documentation just in case. /boot size meter is suboptimal in terms of additional I/O incurred, will be most likely rewritten to make use of advance "du -s".	2013-06-17 19:29:11 +04:00
