[lmi-commits] [lmi] master 6fe3ab7 10/10: Customize /etc/schroot/lmi_profile/fstab

[Greg Chicares]

branch: master
commit 6fe3ab737c9852feae317ecd2526381b420144ef
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Customize /etc/schroot/lmi_profile/fstab
    
    A 'directory' schroot sets up the given mounts on entry, and removes
    them on exit. An 8-4-4-4-12 UUID is appended to the apparent mountpoint,
    which looks like this on the host:
      /var/cache/schroots bound on
        /run/schroot/mount/lmi_bullseye_2-${UUID}/var/cache/apt/archives
    The bind mounts that the 'lmi_setup*.sh' scripts set up should now be
    unnecessary, and they'll be removed soon. For the moment, it appears
    that they can coexist with the new bind mounts.
