(Finally figured out gmail's email alias can be set as default, so my
addy just changed.)
Hi, I have my first program to publish, and would like a little feedback.
zchroot is a bash script to work with encrypted chroot-in-a-file chroots.
--help output is at end of this email.
Right now zchroot is robust for: creating new, showing status of,
mounting and unmounting, encrypted, loopback mounted, chroot in a file
files. Soon I shall double check the robustness of running a command
outside of, or chrooted into, a chroot.
First version I wrote was may be 3 years ago, and at that time I did
not know of schroot.
First version was clumsy, spread over two files, etc.
I started reading schroot docs, man page and config files/ dirs, but
after an hour or two did not to my satisfaction wrap my head around
doing what I really wanted, so bit the bullet and reworked zchroot
into something more palatable than it was.
Last few days (may be I should have read more on schroot :/) I updated
it to this version, which if it's useful to others, I would like to
release.
It may be that schroot can do it all, perhaps with just a little
custom up/down scripts. So if someone is familiar with schroot, I'd
like some feedback on this if you have time.
Quick questions:
*) Should I post zchroot here, plain or zipped?
It is 551 lines, zenlib.sh is 157, and zchroot.conf is 66 lines.
TIA
