Hi All! I'm writing a bash shell script to be executed on a LTSP 5.x client (once copied in /opt/ltsp/amd6/usr/share/screen.d + ltsp-update-image.
The script (started as a SCREEN_O2=srv_launch in lts.conf) starts and execute correctly (backup local mbr/gpt/partitions of windows/linux station to the server). As a simple "exit" in the script just restarts it, I need to include a "shutdown -r now" or "shutdown -hP now" in the script. Then, once the shutdown is called, I get a bunch of error messages on the thin client screen before it reboots ou halts. Unfortunately, I cant'get more details about those, even when syslog is redirected to the server's one. I just know most of those error messages concern squashfs error. I guess the shutdown close the nbd connection while the script is finishing/dying. Taking a look at the (chroot)/usr/share/ltsp/screen_session script, I've found that my script (or any other SCREEN_xx= one) is started in a "while true" loop by the ltsp "screen_session" script. Therefore, once a user script exits (and/or starts a shutdown): a) the screen_session father script tries to restart it b) If it gets enough time to do it, this endless while/true loop restarts effectively the script, causing strange effects, requiring some kind of lock mechanism in the script to avoid a "re-run". c) All this requires the presence of the squashfs-ed filesystem mounted by nbd at startup. d) At one time, the shutdown finally closes the nbd connection, causing an error msg storm on the screen. Q: Unless I modify the screen_session screen (break the while/true loop), what can be done to get a "real/clean" shutdown ?
