Hello,
we have got an embedded platform which has a compact flash as hdc. Currently we boot the system via lilo into ramdisk. This (loading the compressed filesystem of 13mb into ram) lasts about 3 minutes. "Normal" copying from mounted flash into rootfilsesystem after booting takes just about 5 seconds. Can anyone to give me a hint, what could cause this long loading time?
Second question: Would it be possible to get a better booting time by uncompressing the file system, storing it on flash and just loading the dynamical parts (f.e. /var) into ram? How would I have to modify my current system consisting of the mentioned compressed filesystem, kernel (vmlinuz)? Actually I'm not very experienced in "playing" with my own OS.
Thank you for your help.
