ALL PUPs use "delayed write" for all I/Os (as far as I know) But, at shutdown, the system is suppose to "sync" all I/O cache before execution..Smithy wrote:So would it be easy enough to put the UDF code in Zigberts PBurn, either automatically mounting when a UDF disk is inserted or possibly a Load UDF Button? Would be a neat little feature.
Maybe a little premature until a few more UDFs are reported in..
As regards writing to UDF, I'm not sure if any Puppyists want to go through the potential of cd/dvd disks occassionally losing their data, but I would bet UDF writing would be pretty solid in Linux, 'cos it seems really good at those sort of things.
And it usually only happens(ed) when you forget to dismount the thing and it used to freak out. Think write behind caching could catch one out sometimes.
In mounting a Live CD/DVD for active writing, I am not sure how LInux handles that type media when it is mounted and open in write mode. The ideas posted for data loss seemingly ONLY AFFECTs device media opened in wirte mode. In read mode, I fail to see how a "bug" exist to cause data loss on any media, albeit Live media, so that which has been promoted about UDF seems to not be consistent with system operations.
In write mode, any media is exposed to something going wrong so, again, I am not sure whether UDF poses any more risk than any other device.
The biggest question is to determine in Puppy where the founders-developers believe the best place to provide what we get in Apple and Microsoft in the way of UDF.
Further, as mentioned, Puppy does have some PETs which might provide, at least, as a stop-gap, the means to mount and read UDF media. But, again, it depends on whether the developer find time and provides effort for making read ability available for the community to test.
