creds_msdos rc.d script

kfmut

Hi,

I've tried to do a headless install of NetBSD on my RPI from a ready-made image and got a slight glitch with creds_msdos script. File creds.txt created under Win8 OS on boot partition(FAT32) of SD-card when checked from NetBSD for some reason has its name in upper case(CREDS.TXT) and is NOT picked by script. Maybe it would be wise to change creds_msdos script so it will be checking for both variants of filename?

kfmut On MS-DOS FSes, the kernel should always fold cases. If the FS is NTFS, use the -i flag when mounting:

$ sudo mount -t ntfs -o,-i /dev/dk1 /mnt

rvp Sorry, I didn't get what you meant by that, I have no control on the way the boot partition is mounted. I'm referring to this https://wiki.netbsd.org/ports/evbarm/#index4h3

kfmut On MS-DOS filesystems, the case of the filenames don't matter:

# newfs_msdos -F32 /dev/rsd0e
/dev/rsd0e: 15298344 sectors in 1912293 FAT32 clusters (4096 bytes/cluster)
MBR type: 11
bps=512 spc=8 res=32 nft=2 mid=0xf0 spt=63 hds=16 hid=0 bsec=15328256 bspf=14940 rdcl=2 infs=1 bkbs=2
# mount /dev/sd0e /mnt
# echo hello > /mnt/CREDS.TXT
# cat /mnt/creds.txt
hello
# test -f /mnt/CrEdS.TxT && echo file exists
file exists
# umount /mnt

The kernel will fold all case on file access (as long as you don't do any naive string comparisons in your script, or program--and creds_msdos isn't).

rvp I've rechecked it, the script isn't picking up the file when useradd user password string is missing 0x0a line feed character at end. Guess I accidentally wq-ed it when I was checking it with vi, and 0x0a was added to the string so after system reboot the script was able to pick it up.
