casper-snapshot --resync-string:Defaults() wrongly sets COW

[phl]

Binary package hint: casper

casper-snapshot --resync-string:Defaults()' wrongly sets COW from $snap_mount value remembered by initrd/casper:try_snap() line:

echo "export ${snap_type}SNAP="${snap_mount}":${snapdev}:${snapfile}" >> /etc/casper.conf # for resync on reboot/halt

for ROOTSNAP the value of ${snap_mount} is /root but the value of COW should be /cow

for HOMESNAP the value of ${snap_mount} is /root/home but the value of COW should be /home or better /cow/home should /casper directory provide a R/O filesystem with something in /home.

Surely it would be simpler and better just to have /scripts/casper put the right thing in casper.conf to start with? Nothing else other than casper-snapshot uses that, and it seems wrong to have to have it know what the initramfs happened to use as its target directory name.

I'll make the appropriate change.

This bug was fixed in the package casper - 1.178

---------------
casper (1.178) karmic; urgency=low

  * Ensure that unionfs-fuse isn't killed by /etc/init.d/sendsigs on
    shutdown (LP: #386010).
  * Patches from "phl" (https://launchpad.net/~ubuntu-leledy), adjusted by
    me, to fix snapshot resync:
    - Avoid using cpio -u -d options if klibc cpio is in use (LP: #384059).
    - Copy /etc/casper.conf into /root, otherwise we forget snapshot resync
      settings (LP: #384061).
    - Adjust the first field of *SNAP entries in casper.conf to be relative
      to /cow, not /root (LP: #384066).
    - Prefix $DEST with $MOUNTP in casper-snapshot (LP: #384068).
    - /etc/init.d/casper is usually called with 'start', so handle that as
      well as 'stop' to do snapshot resyncing and CD ejecting (LP: #384076).
  * Fix casper-snapshot(1) syntax to avoid missing spaces between options
    and their values.
  * Fix showmounts when used in conjunction with unionfs-fuse; read-only
    filesystems need to be bind-mounted rather than move-mounted.
