Hi list,
I'm currently experimenting with vhashify but I'm getting segmentation
fault whenever I run vserver <name> hashify or
/usr/lib/util-vserver/vhasify.
I'm running debian sarge on amd64 (though I can reproduce the problem on
another machine running on i386). Custom built debian package for
util-vserver-0.30.208-fix2 with beecrypt2 enabled (based on sarge's
package, could make public if someone interested, newbiely built,
though...) and vanilla 2.6.13.4 kernel patched with
patch-2.6.13.3-vs2.1.0-rc4.diff.
testme.sh gives no errors, everything else seems running fine. The
filesystem (if matters) is xfs. Tried both with SHA-1 and MD5 hashing
methods.
These are various outputs:
# vserver webber hashify
Segmentation fault
# touch exclude (blank excludelist)
# /usr/lib/util-vserver/vhashify --manually -nv --destination
/etc/vservers/.defaults/apps/vunify/hash/ /vservers/webber/lib/ exclude
Initializing exclude-list for /vservers/webber/lib/
Starting to traverse directories...

Could give more outputs to/and help track down this bug(?).
Thanks very much for such great project, running flawlesly for couple of
months :)
