Let me state a couple of given's up front:
1) I would post this on a FreeSBIE list if I could find one.
2) I think the issue I have right now is not understanding completely the
limitations of cpio.
My problem is that when building the file system to use for making the iso
cpio fails when copying some of the files saying "Operation not permitted".
These are some of the files fairly important to the operating system like
libexec/ld-elf.so.1 and lib/libc.so.7.
I don't see any reason for copying the other 16,540 files and failing on
these 22 important files.
Can anyone point me in the right direction for a better understanding of
what's going on, or even just call me an idiot and tell me the simple thing
I've missed? Either will be appreciated.
Joe.
<Details>
I'm using 8.1-STABLE FreeBSD 8.1-STABLE #2, and freesbie-2.0.20070710 from
ports. I've updated the kernel conf file to match GENERIC, with the
following lines from the original FreeSBIE kernel added at the end:
device bktr
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_DEFAULT_TO_ACCEPT
device pf
device pflog
device pfsync
options IPSTEALTH
options IPDIVERT
options GEOM_UZIP
options GEOM_LABEL
options VESA
options SC_PIXEL_MODE
The system seems to build fine but hits a snag in this section of the
script:
# If FILE_LIST isn't defined...
if [ -z "${FILE_LIST:-}" ]; then
# then copy the whole filesystem
find . -print -depth | cpio -dump -l -v ${CLONEDIR} >> ${LOGFILE}
2>&1
else
# else pass it to cpio
... more code to dump filenames from ${FILE_LIST} to cpio ...
fi
If I try to run it manually on one of the files that fails, I get this:
slug# echo "/usr/local/freesbie-fs/libexec/ld-elf.so.1" | cpio -dump -l -v
/usr/local/freesbie-clone
/usr/local/freesbie-clone/usr/local/freesbie-fs/libexec/ld-elf.so.1
cpio: Can't create '/usr/local/freesbie-clone/usr/local/freesbie-
fs/libexec/ld-elf.so.1': Operation not permitted
0 blocks
I can use cp to copy the file, so I don't understand what's going on here.
Does anyone have any ideas?
