[lfs-support] lfs 8.2 - how to resume session

[lothar]

hello,

i am in lfs 8.2 book 6.2.20, gcc, where i encountered the trouble that the test runner hung.
i killed the test runner.
in xb/gcc/testsuite/gcc/gcc.log, there were 127959 PASS, 0 FAIL, 366 XFAIL records.
i believe the test runner was in a loop.

i left my session and came back hours later and wanted to resume my chroot session and retry the build.
i gave the commands shown below from lfs 8.2 book 6.2.2, 6.2.3, 6.2.4 to resume the chroot session.
i made a fresh copy of gcc-7.3.0 sources, and did the config and make from lfs 8.2 book 6.2.20.
when i ran the test suite, every test failed.
in xb/gcc/testsuite/gcc/gcc.log, it looks like every FAIL case has the 3 lines

FAIL: # text with test case name
Excess errors:
spawn failed

my question is, how can i quit my chroot session and resume it later so that the builds work properly.

the commands i gave to resume the chroot session are shown here:

Just a silly question, was the LFS variable set?

Also, the following is missing:
if [ -h $LFS/dev/shm ]; then
mkdir -pv $LFS/$(readlink $LFS/dev/shm)
fi

That one is not needed now that the /etc/passwd files has been created.

You had deleted the previous build directories, haven't you?

Apart from what has been said above, there is nothing obvious I can see.

Did you do this in your new session?

If any members of GCHQ are reading this, shame on you! I fought for
your right to belong to a trade union and now you are taking away my
right to privacy?
