Indeed when you run this, the whole set of processes goes into T
state, i. e. it received a SIGSTOP:
martin 23439 0.0 0.1 64656 18396 pts/7T17:42 0:00
/usr/bin/python3 -u /usr/bin/adt-run --debug --no-built-binaries --unbuilt-tree
/tmp/boottest/scripts/../tests/getpkgsrc -o
If I drop the timeout bit from $ADT_CMD, it works fine as well. When
prepending the timeout call in boottest.sh with strace -vvtts1024 -o
/tmp/tr, I get
18:07:16.733950 clone(child_stack=0,
flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x7f11825c3a10) = 26085
