I posted this <http://forum.ipxe.org/showthread.php?tid=3730> in the iPXE forum and was directed to try the dev mailing list.
While messing around with iPXE loading multiple initrd files I ran into an issue with file permissions not being maintained. Here is my iPXE script: #!ipxe kernel http://web/boot/vmlinuz initrd http://web/boot/core.gz initrd http://web/boot/bootlocal.sh /opt/bootlocal.sh boot Here is the listing for /opt/bootlocal.sh in core.gz directory: 4 -rwxrwxr-x 1 root staff 51 Mar 4 2010 bootlocal.sh Here is the listing for http://web/boot/bootlocal.sh: 4.0K -rwxrwxrwx 1 root root 38 Aug 1 13:33 bootlocal.sh For reference, core.gz is from TinyCore 4.5 and http://web/ is CentOS 6 (not that I think it makes a difference, just trying to be thorough). The script works. The system boots up and /opt/bootlocal.sh (which already exists in core.gz) is overwritten by http://web/boot/bootlocal.sh, except that it no longer has the permissions that exist on the original bootlocal.sh in core.gz or on the web server copy. Along with new permissions it's got a new date stamp of Jan 1, 1970... so basically it's dropping all meta-data and umask is setting default create permissions. Digging through the iPXE source I found the acquire function that actually pulls the file off the server, and it's pretty much just wget (if I'm reading this right), which explains why I'm losing file permissions and such. Which finally leads me to my question: how can I set file permissions in iPXE after the file has been acquired? -Bryce
