Right. I've recompiled autofs(had to include MIT Kerberos)and the results were intially promising. 'automount -v -f -d /etc/auto.master' gave: Starting automounter version 5.0.7, master map /etc/auto.master using kernel protocol version 5.02 lookup_nss_read_master: reading master file /etc/auto.master parse_init: parse(sun): init gathered global options: (null) lookup_read_master: lookup(file): read entry /testautomount master_do_mount: mounting /testautomount automount_path_to_fifo: fifo name /run/autofs.fifo-testautomount lookup_nss_read_map: reading map file /etc/auto.testautomount parse_init: parse(sun): init gathered global options: (null) mounted indirect on /testautomount with timeout 300, freq 75 seconds st_ready: st_ready(): state = 0 path /testautomount Then after approx. 1min st_expire: state 1 path /testautomount expire_proc: exp_proc = 3060792128 path /testautomount expire_cleanup: got thid 3060792128 path /testautomount stat 0 expire_cleanup: sigchld: exp 3060792128 finished, switching from 2 to 1 st_ready: st_ready(): state = 2 path /testautomount However, when inserting the usbstick and try and list any contents, it is only on /testautomount, i.e. the dir. sandisk is not available and can not be created: mkdir: cannot create directory '/testautomount/sandisk': Permission denied.
