Dear Linus,
you are absolutely correct, my mistake. I was using 7zr and not 7z.
For 7z to be supported changes have to be done to archivemount.
Can you support those changes?
Cheers,
Chris.
P.S: You are also correct for libarchive, it is Version: 3.0.4-2 now.

Dear Linus,
Hi Chris,
Thanks for your explanations. Hmm, are you sure Debian Sid has libarchive
2.8.5? I'm getting:
---
$ aptitude show libarchive12 | grep Version
Version: 3.0.4-1
---
And 3.0.4 seems to be the latest stable release of libarchive
according to libarchive.github.com.
And although libarchive 3.0.4 is supposed to support .7z archives, the
following commands do not work for me, the mount point remains empty:
---
$ mkdir /tmp/mytestdir/&& \
mkdir /tmp/mytestdirmount&& \
echo "foobar"> /tmp/mytestdir/testfile&& \
7z a /tmp/mytestdir.7z /tmp/mytestdir&& \
archivemount /tmp/mytestdir.7z /tmp/mytestdirmount&& \
mount | grep "archivemount"&& \
ls -lah /tmp/mytestdirmount

So I'm a little confused now, is this a missing feature in
archivemount (as I initially thought) or a bug in archivemount or
a bug in libarchive? Or a bug in front instead of inside of my laptop :)?
Cheers, Linus
there is no problem if you already have installed libarchive version
= 0.3.0. It supports .7z archives, so archivemount will handle such
archives by default, no changes needed. Bare in mind that
archivemount is a "high-level wrapper" for libarchive, so everything
libarchive supports is supported also by archivemount.
Wheezy/SID supports only libarchive-2.8.5-5 version for the moment.
I believe that you should file a new bug to the libarchive
maintainer to support the new version.
Regards,
Chris.

Hi,
just tried using archivemount with a .7z archive, but it unfortunately
didn't work, the mount point is empty.
Before I tried archivemounting a .tar.xz which worked fine, but
unfortunately also took a while on this 1GB+ archive.
I'm not really into the details of compression algorithms and their
container formats. But I'd guess that theoretically mounting a .7z
archive should be much faster as the directory and file information are
somehow more easily accesable, therefore not requiring to uncompress the
whole archive before getting that information compared to .tar.xz, right?
At least with 'ark' displaying the archive contents is instant with a
.7z, while with the .tar.xz it again takes a while.
As both .7z and .tar.xz use LZMA, the size of those two is pretty much
the same. Therefore .7z could be a supperior solution to .tar.xz or
.tar.lzma for archivemounting?
Looks like .7z is supported by libarchive, too.
Cheers, Linus
