Hello! Recent versions of FAI 4.0 in experimental have a new variable, FAI_RAMDISKS, which replaces the FAI_NORAMDISK in older versions.
The only documentation (besides the warning issued if the old variable is used) seems to be in http://wiki.fai-project.org/index.php/Variables and that does not document an important use case: what to put into the variable if I do not want any ramdisks to be used (eg if RAM is scarce). I tried 'unset FAI_RAMDISKS and 'FAI_RAMDISKS=""', neither of which led to the desired effect: the default value $target/var/lib/dpkg gets assigned just prior to its use in /usr/lib/fai/mkramdisk any time the variable is unset or empty. The code in /usr/lib/fai/mkramdisk contains a check whether the would-be ramdisk will be mounted on an existing direcory. Thus, if I assign a non-directory value (eg "NONE") to FAI_RAMDISKS, I should achieve the desired effect or not having any ramdisks mounted. I think that this case should be better documented, and perhaps a special value (such as NONE) should be tested for in mkramdisk ? Toomas
