Feedback on Working With LFS-Based SI
I started working with the LFS-based sample implementation a couple of
weeks ago and would like to share some of things I found to see if others
have seen the same thing or to find out what I did wrong. Here's what I
found.
1. Originally I worked with the manual process documented on the Linux From
Scratch web site. One of the beginning instructions tells you to create a
separate filesystem for the build and to mount it at /mnt/lfs. This causes
a problem with the multi-phase build of the SI because at some point it
tries to move /mnt/lfs to /mnt/lfs-harness. This produces a failure saying
/mnt/lfs cannot be removed since it is currently being used. The basic
problem is you cannot move a directory when it is the mount point for a
mounted filesystem. To get around this problem I simply mounted the
separate filesystem at /mnt. There may be other ways to fix this, such as
mounting the filesystem at /mnt/si and then modifying the xml files to use
/mnt/si/lfs instead of /mnt/lfs.
2. The next problem I ran into was when it came time to build dummy-mta.
The src/si/entities/package is looking for the dummy-mta-1.2.tar.gz file,
but the pub/lsb/impl/lfs-si-update-20020508.tar.gz file has
dummy-mta-1.1.tar.gz. This mismatch causes the build to fail. Apparently
someone else figured this out because now there is a dummy-mta-1.2.tar.gz
file in the pub/lsb/impl directory. Since this was not available when I
doing my testing I worked around the problem by extracting the
dummy-mta-1.1.tar.gz file, changing the directory name from dummy-mta-1.1
to dummy-mta-1.2, and then creating a new dummy-mta-1.2.tar.gz file. This
got me by the problem, but it didn't solve everything as demonstrated by my
next item.
3. After creating the dummy-mta-1.2.tar.gz file things went much further in
the build, but after two hours and thirty-five minutes it failed again when
trying to do "make install" on the dummy-mta-1.2 package. The makefile is
very simple only putting a sendmail file in /usr/sbin and then making a
symbolic link to /usr/lib/sendmail. This works fine in one of the earlier
phases, but it fails in the last phase because the sym link was already
there. To fix this problem I edited the makefile in dummy-mta-1.2 to use
"ln -sf" instead of "ln -s". After making this fix I was able to complete
building the si.
4. After having the si completely built, I next tested to see if all the
commands listed in the LSB spec were in the si. The only one I found
missing was /usr/bin/lsb_release. To resolve this I copied the
/usr/bin/lsb_release and /etc/lsb-release files from my Red Hat 7.3 system
to the si.
5. Next I ran lsblibchk on the si to see if all the libraries were there.
It reported all the X11 libraries as missing. I seem to remember someone
saying this was a known problem and was being worked on.
6. The other general question I have is how to restart nALFS so it can
continue the build. When I was testing and ran into the problems described
above, each time I deleted everything in /mnt/lfs and started over. It
seems to me there must be some way to resolve the immediate problem and
pick up where nALFS left off. I would appreciate it if someone could tell
me if this is possible and how to do it.
