About compiling in ram.

[Sandro]

Hi to all

shm                     /dev/shm        tmpfs           exec,rw,mode=1777      0 0

I use this method and by default i've shm = 8 GiB (ram is 16 GiB).

I compile all in ram without troubles; only for debian kernel I had necessity of more ram (however i'm a gentoo-sources user)... solved increasing the size of /dev/shm from 8 to 16 GiB.

 

It is a good choice or there are better ways (for example about security or other things) ?

 

Thanks for answers.
