is there a length limit on the line of parameters passed to isolinux.bin ?
Hi all To perform AutoYAST installs, we use a custom boot CD based on the boot CD that ships with SLES8 SP2a The isolinux.cfg file has been tweaked to contain our standard install parameters (config and rpms repository, for instance) At the boot prompt, we append additional per-server parameters like the hostip, which makes the line even longer The install process works fine on some servers but fails on some others, noticeably on ones located on differnet subnets. Switching to the log displayed on tty3, we eventually found out that it fails when the line of parameters exceeds a certain length. The last characters are dropped, so the gateway IP is truncated and linuxrc fails of course to reach the repository Is this a known issue with isolinux ? What is the authorized length ? Is there a workaround ? Thanks in advance for your help. Francois BLAES ? Global Unix Team ? Mars ISI DDI *170 1639 ? Tel +33 (0) 3 88 05 16 39 ? Fax +33 (0) 3 88 05 16 79
Hi, Yes, there is a limit, I am not sure what is it though (someone telling me it is 256). To avoid this, use an info file with all parameters. Anas francois.blaes@eu.effem.com wrote:

Will this be fixed in SLES9? - I seem to remember it was less then 256. It is easy creating multible prompts in the isolinux.cfg but to be able to use multible info files you would have to have multible initrds. Best regards Hubba Anas Nashif wrote:

not really, you can specify the location ofthe info file on the command line too, for example, info=file:/blah See http://www.suse.de/~nashif/autoinstall/9.0/html/appendix.linuxrc.html Anas
