Hello, I need to generate a unique ID, so far I''ve unit tested this under 100000 iterations and it seems to work : now.to_i.to_s + ''-'' + now.usec.to_s + ''-'' + rand(1000).to_s Is there a better way ? Thanks Notes : 1) without usec, few percents of generated values are not uniques 2) the id generated is a string so the presence of

...states, "This volume of IEEE Std 1003.1-2001 does not define the domain in which the return value is unique." Perhaps uniqueid should be keyed off of a UUID for the system. RedHat provides /etc/sysconfig/hw-uuid. I could not find the standard equivalent on Ubuntu, but you could pipe uuidgen into a file and have facter read from that. -g -- Garrett Honeycutt Sr. Systems Engineer Direct > 800.556.5829x2555 Fax > 206.728.1500 www.speakeasy.net Voice * Data * Managed Services

This patcheset fixes errors in virt-sysprep and virt-sparsify. Here we have a common functionality: is_btrfs_subvolume. Doesn't it make sense to turn it into guestfs API? Also I found an issue. In 'virt-sysprep fs-uuids', the uuids for ALL filesystems are regenerated as many times as many roots are in guest. Is it done intentionally? Maxim Perevedentsev (3): mllib: add checking

...p I found with some digging that I needed to change the UUID of the drive to be able to mount it separately from the existing array.? I used "sgdisk -G /dev/sdg1" to do this.? It worked, but gave quite a few scary warning messages in the process.? A better idea would have been to use uuidgen to generate a random uuid and then start the array like this: ??? mdadm --assemble /dev/md99 --update=uuid --uuid=<newuuid> /dev/sdg1 (might require --force for a broken array, I'm not sure since I didn't actually do it this way) Once the array is running, there is another problem...

Hi, I install a guest Fedora inside the host Fedora. When I use the service xend status to check the status of xend. It shows xend is running. However when I use xm create xen1 to start the guest domain xen1, it failed. The corresponding file xen1 is in /etc/xen/xen1. The error msg is as follows: [root@phillis xen]# xm create xen1 Using config file "./xen1". Going to boot Fedora

I'm trying to build xapian-core-1.2.2 on Linux. After manually installing uuid.h and libuuid.a from e2fsprogs-1.41.12, I receive the following configure error: checking for uuid.h... yes checking for uuid_create... no configure: error: uuid.h found, but uuid_create() not found.
