    290290some of those libraries may come with debugging symbols built in as an alternative package, others can be buiolt from scratch and installed with debugging sysmbols installed. Using your distribtuion's standard built process is probably a good idea for this.

     292= Getting the entire kernel log on restore media =
     293
     294The kernel ring buffer that '''dmesg''' reads defaults to 32k on recent kernels. This is not enough to capture the entire sequence of kernel message when Mondo Rescue boots off a restore media.
     295
     296To increase the kernel ring buffer to 128k at boot time (and without recompilation) add the following kernel boot parameter:
     297{{{
     298log_buf_len=128k
     299}}}
     300e.g.
     301{{{
     302expert log_buf_len=128k
     303}}}
     304'''dmesg''' needs to be told what buffer size to use to ensure that everything is displayed from the start. The '''-s''' parameter can be used for this like this:
     305{{{
     306dmesg -s 131072 | less
     307}}}
