Hi, (I cross-posted this to devel as this is interesting also to them. When replying, you could remove e.g. "users" list as I don't think this applies that much to normal users anymore.) ext Laurent GUERBY wrote: >> You can enable them for all applications by creating a "core-dumps" >> directory to the external MMC. >> >> Unfortunately the cards are mounted with "user" user, so processes >> like "dsnmasq" which are run as user "nobody" cannot dump core to >> the MMC unless you re-mount it so that everybody can write there >> (and even then you don't always get core dumps from segfaulted >> processes for some reason). > > I tried mount -o remount,rw /media/mmc1 but "nobody" didn't > seem to be able to create a file in /media/mmc1/core-dumps/ This doesn't make /media/mmc1/ writable by everybody.

This works: umount /media/mmc1/ mount -t vfat -o rw,nodev,nosuid,utf8,uid=29999,shortname=mixed,dmask=0000,fmask=0133 /dev/mmcblk1p1 /media/mmc1 Check also that: ulimit -c unlimited is run before DSME[1] in linuxrc (on initfs). [1] which (re-)starts the dnsmasq proccess along with many others... - Eero
