(I'm forwarding this from comp.os.linux.help - I'm having the same issue with FAT32)
hey all,
I have a removable, USB disk (ikebana) that I'm trying to use as a portable storage device (ie: developing programs for Win32, macosx and linux simultaneously)
Anyways, everything is sort of working except for execute privileges on linux (win32 works, macosx works). When I try to execute something, I get:
bash-: ./a.out: Permission Denied
When I try to execute a shell script (even as root), I get:
-bash: ./aa.sh: /bin/bash: bad interpreter: Permission denied
Now, I understand that FAT32 has no execute bit.. however I explicitly set (or an automatic process on SuSe linux set the fstab entry for the drive to be:
/dev/sda1 /windows/D vfat users,gid=users,umask=0002,iocharset=iso8859-1,code=437 0 0
which as I understand it sets the permissions to be 775.
Argh! so I would expect this to work transparently.
So... is there a bug in the kernel, default settings, is something missing in the above entries, or what? I'll escalate this to linux-devel if it looks like there is nothing wrong with the above..
forgot to mention -
When I'm writing to FAT32 partition, there seems to be a 300% incurred size penalty over the equivalent files on ext2 (when unpacking a source distribution like boost, gcc, etc)
Is this an artifact of the FAT32 file system, a bug in the linux IO to the FAT32 file system, or a local bug in my system?
I'd like to get this resolved, but understand if its a microsoft issue... however it would be really, really nice if NTFS was supported (ie: if linux could write files on NTFS..) I have a sneaky suspicion that FAT32 isn't the greatest and only used on these drives because it is the lowest common denominator.
