[Ltib] Customizing the RFS layout

[Anthony L. Montiel]

I am working on a project in which I plan on having a read-only root filesystem. I expect I'll use either CRAMFS or SquashFS. Whichever I choose, there is still a requirement for some non-volatile (i.e. writeable and persistent) locations in the filesystem (/var for example). So I plan on creating a JFFS2 partition in my flash and mount that  as /var. I'll use TMPFS for /tmp.

 

Questions:

1) Is there an example of doing this under LTIB? Specifically, creating two filesystems (say CRAMFS and JFFS2) within the LTIB build structure.

2) I am using the i.MX27 ADS release ISO as my starting point. Is there any advantage to using a "fresh" LTIB, rather than the pre-packaged version?

 

Thank you for your time!
