SO I have cut down the configuration files to a minimum:

petal# cat /etc/auto.master
#DIR            [TYPE[,FORMAT]:]MAP                     [OPTIONS]

/-              file,sun:/etc/auto.mp
petal# cat /etc/auto.mp
# vim:set ft=conf sw=2 noet nowrap:

/mp/mumon/._    -fstype=btrfs,ro,rw,exec,suid,nossd,lazytime
:/dev/mapper/peL0p7

petal# automount -f -d3
Starting automounter version 5.1.9, master map /etc/auto.master

do_init: parse(sun): init gathered global options: (null)
do_spawn: >> mount: /tmp/autoP0xIB3 bound on /tmp/autocrpfww.

Aborted (core dumped)

Happens also with direct mounts (even if I mostly use indirect ones):


petal# cat /etc/auto.master
#DIR            [TYPE[,FORMAT]:]MAP                     [OPTIONS]

/mp             file,sun:/etc/auto.mp
petal# cat /etc/auto.mp
# vim:set ft=conf sw=2 noet nowrap:

mumon/._        -fstype=btrfs,ro,rw,exec,suid,nossd,lazytime
